Subject: [NET_SCHED]: sch_cbq: fix cbq_undelay_prio for non-active priorites
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e9054a339eb275c756efeeaee42af484ac72a3f4;p=openwrt%2Fstaging%2Fblogic.git

[NET_SCHED]: sch_cbq: fix cbq_undelay_prio for non-active priorites

cbq_undelay_prio is supposed to return a time delta, but returns the
current time for non-active priorities, causing cbq_undelay to mark
the priority as active and schedule a timer for twice the current
time.
